Gear Box Z R+ Programmer
Dean E (Missouri) 3/21/2012 5:15 PM
Easy to use, just follow voice commands. Only issue I had was after install I found my truck speed reading about 5 MPH too fast compared to my GPS. Called tech line and stated there was a software glitch. Sent another programmer and did a recovery then reinstalled program and worked as advertised. Have not taken a big trip yet but city and back road driving MPG is up at least 2-3. Get on it and WOW, what get up and go for a 7000 lbs truck. Just like running a geared up big block muscle car. No EGR block off plate needed. Just unplug the EGR valve since it is closed relaxed and is powered open. Easiest way to get what you expect from your Duramax.
